Polymer solution has extremely extensive applications in many natural and industrial processes, especially oilfield development field, such as polymer flooding, fracturing water shut-off. Thus, the study of flow behaviors formation pores is significantly important. In this paper, droplets 3-D pore throat structure were systematically studied. Additionally, influencing factors (polymer concentra...

The major N-containing polymer compounds in the body include protein, RNA, and DNA. The endogenous gastrointestinal secretions as well as the portal-drained visceral and peripheral immune responses are basic physiological functions. Elevated endogenous secretions and immune activities, as affected by developmental stages, diets, and management factors, decrease the availability of dietary nutri...

The DFLU numerical flux was introduced in order to solve hyperbolic scalar conservation laws with a flux function discontinuous in space. We show how this flux can be used to solve systems of conservation laws. The obtained numerical flux is very close to a Godunov flux. As an example we consider a system modeling polymer flooding in oil reservoir engineering. Key-words: Finite volumes, finite ...

Oil is an important non-renewable resource for the world. The application of alkaline-surfactant-polymer flooding has successfully enhanced the oil recovery in Chinese oilfields. The oilfield produced water is the layer water that came from the oil well along with the oil in the alkaline-surfactant-polymer flooding. Thus, the treatment process of oilfield produced water to meet the reinjection ...

Most of Indonesia’s oil field has been producing the for long period time. For this reason, enhanced recovery (EOR) method becomes most promising to improve production country. Chemical flooding, especially polymer flooding is simplest and commonly applied chemical technique, since it can be used after water process. Screening considered first step in evaluating selecting potential polymers res...
